ZnO-modified cellulose fiber sheets for antibody immobilization
(Elsevier Sci Ltd, Oxford, 2014)
Cellulose fiber sheets impregnated with saccharide capped-ZnO nanoparticles were used as bioactive materials for antibody immobilization. First, ZnO nanoparticles were synthesized in the presence of glucose (monosaccharide), ...
A comprehensive approach to in vitro functional evaluation of Ag/alginate nanocomposite hydrogels
(Elsevier Sci Ltd, Oxford, 2014)
In this work, we present a comprehensive approach to evaluation of alginate microbeads with included silver nanoparticles (AgNPs) at the concentration range of 0.3-5 mM for potential biomedical use by combining cytotoxicity, ...
Sorption properties of TEMPO-oxidized natural and man-made cellulose fibers
(Elsevier Sci Ltd, Oxford, 2009)
Cotton and lyocell fibers were oxidized with sodium hypochlorite and catalytic amount of sodium bromide and 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO), under various conditions. Water-insoluble fractions, collected ...
Response surface methodology for optimisation of edible coatings based on dextran from Leuconostoc mesenteroides T3
(Elsevier Sci Ltd, Oxford, 2018)
The aim of this study was to develop dextran-based edible films plasticized by sorbitol. In order to optimise the film-forming formulation, response surface methodology was used. The influence of dextran and sorbitol ...
Novel modified nanocellulose applicable as reinforcement in high-performance nanocomposites
(Elsevier Sci Ltd, Oxford, 2017)
The influence of modification and vacuum/supercritical CO2 (scCO(2)) drying methods on the surface properties, morphology and thermal stability of cellulose nanocrystals (NC) was presented in this study. Introduction of ...
Synthesis and antimicrobial properties of Zn-mineralized alginate nanocomposites
(Elsevier Sci Ltd, Oxford, 2017)
New bioactive and antimicrobial biomaterials were produced by alginate-mediated biomineralization with Zn-mineral phase. The synthesis procedure is simple, cost-effective and resulted in. two different Zn-mineralized ...
Mineralized agar-based nanocomposite films: Potential food packaging materials with antimicrobial properties
(Elsevier Sci Ltd, Oxford, 2017)
New mineralized, agar-based nanocomposite films (Zn-carbonate and Zn-phosphate/agar) were produced by a combination of in situ precipitation and a casting method. The presence of minerals significantly influenced the ...
Stability of TEMPO-oxidized cotton fibers during natural aging
(Elsevier Sci Ltd, Oxford, 2020)
Stability of cotton fibers oxidized by the 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO)-mediated system during natural aging was monitored; the oxidized and five-year-aged fibers were characterized in terms of ...
Alginate/soy protein system for essential oil encapsulation with intestinal delivery
(Elsevier Sci Ltd, Oxford, 2018)
Preparation of alginate-soy protein isolate (AL/SPI) complex beads containing essential oil of thyme was carried out by emulsification of thyme oil in aqueous sodium alginate solution blended with SPI solution, followed ...
Design of pectin-sodium alginate based films for potential healthcare application: Study of chemico-physical interactions between the components of films and assessment of their antimicrobial activity
(Elsevier Sci Ltd, Oxford, 2017)
In this study, pectin based films including different amounts of sodium alginate were prepared by casting method. All the films, with and without polyglycerol as plasticizer, were crosslinked with zinc ions in order to ...
